Works for me. Just ran the 3.2 RC2 installer and did the following:

(type is like a Windows equivalent of `cat` on *nix) 

>type test.py
import sys
print(sys.version_info)

>test.py
sys.version_info(major=3, minor=2, micro=0, releaselevel='candidate', serial=2)


Additionally, "Edit with IDLE" shows up when right clicking on the file.

Did you get any errors when running the installer? What permissions does your account have?
